FIELD

The present technique relates to generation of a personalized video content. More specifically, the technique relates to dynamic generation of personalized video content in a conversational interface using web technologies.

BACKGROUND

Companies constantly look for providing distinctive experience for their customers by not only providing important information, but also emphasizing the relevance of that information. Making every communication count is one of the key differentiators in the field of customer experience. For example, in an insurance company, there may be multiple communication channels through which an insurer interacts with the customer; from sending out flyers and prospects to providing quotes, leads and statements. Often, the customer either fails to read the important information from these verbose documents or has difficulty in understanding them. These communication gaps lead to disengaged customers, which in turn may lead to repeated customer service interactions, and subsequently, a dissatisfied customer, and lower conversion rates.

In the past few years, videos are replacing the plain, boring, textual content online. It is generally in the form of mass marketing content, which is still less effective, as it lacks personalization. Customers still need to go through information to filter out and understand what is relevant to them and what is not. Customers thus have begun to expect communication that is tailored to their needs, instead of mass marketing.

One of the approaches to deliver personalized video experience is by creating one video per person. In this approach, content management is cumbersome, as every unique personalized video generated for each user needs to be stored in a database and hosted on server. The content also needs to be optimized for delivery across multiple devices and streamed thereof. This process is not very scalable. As the number of users increase so do the number of videos. Management of those videos and delivery become cumbersome over a period. It is also extremely expensive, considering production costs, storage costs, and delivery costs. The requirement of extensive setup for delivery of large volume of videos make the process cumbersome. Also, other personalized video offerings in market, the generation happens using server-side technologies, which would consume huge processing power and would need personal data to be passed to personalized video processing servers. All these costs more infrastructure, processing time, and effort. Passing on personal data to video processing servers brings responsibility for personalized video service providers to add security checks to protect data. Hence there is need to overcome the above-mentioned problem.

SUMMARY

Presently, most of the personalized video experience to the user is achieved by generating video for each person or the processing of the video is performed on servers, stored and the streamed to the user based on the user request which may consume more resources of servers and network.

In one or more embodiments, the client device 202 may comprise personalized video generation engine 224 which is described in detail in subsequent paragraphs.

In one or more embodiments, the chatbot platform 212 may comprise one or more components but not limited to a chatbot engine 214, a conversation database 216, a response generator 220 and/or a response widget library 222. The chatbot engine 214 (also referred as ‘conversation engine’) may be communicatively coupled to the conversation database 216, the external data source 218 and the response generator 220. The response generator 220 may be configured to communicate with response widget library 222.

The chatbot platform 212 may be configured to receive user inputs (also referred as ‘user utterances’) from the client device 202 through the chat application 206, compose responses and send it to the client device 202. The chatbot engine 214 may be configured to interpret user utterances using Natural Language Processing and determine the relevant response to the received user utterances. The chatbot engine 214 may determine the response based on configuration of the chat application 206, conversation context of the user utterances fetched from the conversation database 216 and/or user data fetched from the external data store 218. The conversation database 216 may be configured to store previous conversation data of the user and context associated with previous conversation data as a part of user interaction with chat application 206.

The external data source 218 may be configured to store information (also referred as ‘user data’) associated with the user. The external data source 218 may comprise various types of information provided by the user (e.g., demographics data, personal information, geo-location data etc.) and associated with a specific entity that user is associated with (e.g. car insurance, bill statements, customized information for user). The entities may comprise information which is personalized for the user. For example, the user may hold a Health Insurance account and the external data source 218 may contain information such as plan chosen by the user, premium amount, coverage etc. In other examples, the external data source 218 may include information from third-party sources such as, but not limited to, credit card companies, banks, social networking websites and/or email services. The user profile may be a part of external data source 218 and may be configurable by the user via a network application (e.g., a web page), which may comprise preferences of the user on what information and how such information to be communicated to the user. The chatbot engine 214 may be configured to access user data from the external data source 218 only when such requirement is identified based on the intent of user utterances. For example, the user may ask the chat application 206 to show meeting scheduled for next two days. The chatbot engine 214 may determine the intent from the user utterance that response should be the calendar details and may fetch the calendar details from the external data source 218. Another example wherein the user may request the chat application to show the savings account balance in which case the savings account details may be fetched from external data source 218.

In one or more embodiments, the user data may comprise confidential information based on the pre-defined attributes associated with the user data. In some cases, the user may choose to set the user data or part of user data to be confidential, by selecting attributes associated with the user data. For example, account number, mail ID and/or credit card number of the user may be ‘confidential’. Also, the user may mark the account balance information as ‘confidential’. In cases where the user data is marked as ‘confidential’ and such user data to be presented in a personalized video, the user may be authenticated before extracting the user data from the user data sources. The user may be authenticated by prompting user to enter the user ID, password or any credentials at the client device or through the chat application 206 to authenticate the user which ensures that the personalized video which may sometime comprise confidential information or any such tailored information is accessed by the intended user only. The user data for example, in case of utility bills for a user may be, but not limited to person name, bill amount, due date and/or reward points. In another example, for an auto insurance offer, the user data may be, but not limited to, purchaser name, purchased vehicle make, vehicle model and/or premium amount.

In one or more embodiments, the user data of a user may be extracted by the client device 202 encoded in the form of Uniform Resource Locator (URL) received as query parameters or relative URLs from the chatbot engine 214. In such cases, the user data may be extracted from the URLs or any webpage associated with the URLs and such data may be extracted by parsing the webpage.

The chatbot engine 214 may be configured to save each conversation data in the conversation database 216. The chatbot engine 214 may also be responsible to update user data stored in the external data source 218 when such requests are received from the user though chat application 206. The chatbot engine 214 may be configured to send the determined response i.e., intent that is determined for the user input and user data received from the external data source 218 (whenever required based on the determined intent) to the response generator 220. The response generator 220 may be configured to interpret the response received from the chatbot engine 214 and may determine a format in which the response to be communicated to the user with the help of the response widget library 222. The response widget library 222 may be configured to store collection of response widgets which comprises configuration information of all UI (user interface) elements that may be presented as a response/message to the user at the chat application 206. The response/message may be of type, but not limited to, text, buttons, editable forms, images, audios, videos and/or ‘Personalized Smart Video’ (personalized video content). The response generator 220 may be configured to select one widget from the response widget library 222, populate the widget with response received from the chatbot engine 214 and compose a data package. The composed data package may be sent to the chat application 206.

In one or more embodiments, the chat application 206 may be configured to identify the format of the data package. If the format of the data package may be any of text, buttons, editable forms, images, audios and/or videos, then the response may be processed by the chat application 206 as per the configuration and the message may be displayed to the user.

In one or more embodiments, if the format of the response is of type ‘Personalized Smart Video’, the chat application 206 may be configured to extract the user data and information of attributes of the personalized video content from the data package and send it to the personalized video generation engine 224. It is to be noted that if the widget selected by the response generator 220 while composing the data package is of the type PSV, then the selected widget may comprise information related to attributes of the personalized video content. The information of the attributes of the personalized video content may comprise information such as, but not limited to, user preferences for personalized video and/or storage location information (storage path) of a video template and associated video configuration metadata file stored in the PSV web server 226 (also referred as ‘storage server’).

The chatbot engine may determine intent of the received user input (also referred as user utterances) using Natural Language Processing (NLP) component configured/trained to determined intent, as in step 404. The chatbot engine may identify a response to be sent to the user based on the determined intent. The chatbot engine may fetch the response from either from conversation database or external data source or combination thereof, as in step 406. The chatbot engine may communicate with conversation database to determine and receive the response for the user input. The response obtained from the conversation database may be such data associated with the previous conversation of the user or the preconfigured responses stored at the conversation database as a part of configuration of the chatbot platform. The external data source may be a storage server configured to store user data which is such information that user requests at the conversational interface. The external data source may be domain-based data store, for example, financial, medical, insurance, social security etc. The chatbot engine may communicate the response received from the external data source and/or conversation database to the response generator. The response generator may determine response type (or format), as in step 408, based on the content present in the response received from the chatbot engine. The format of the response may be such as, but not limited to, image, action button, editable forms, text, video and/or personalized smart video. The format of the response may be determined based on at least one of but not limited to, the content of the response that needs to be delivered to the user, specific request made by the user as a part of user input and/or preferences of the user. The response generator may communicate with the response widget library and receive the response format configuration data. The response widget library may be configured to store one or more configurations for the responses for the format such as, but not limited to, image, action button, forms, text, video and/or personalized smart video. The configuration defines the UI elements which displays the response at the conversation interface. The response generator may append the response received from the chatbot engine with the configuration received from the widget library to compose data package of the determined format, as in step 410. The response generator may send the data package to the conversational interface, as in step 412.

In an example embodiment, consider a customer/user is looking for car insurance quotation (quote). The user may visit insurance provider website, interacts with the chat application. The chat application may ask whether user is looking for car insurance. When the user responds ‘yes’, the chat application may ask details such as—person name, car details (make, model, year etc.), address and desired coverage limits etc., either through a text format or an editable form format, as per the configuration at the chat application and chatbot platform. The chatbot platform may store inputs received from the user as pervious conversation and as context associated with previous conversation in the conversation database. Once required information to provide a quote is captured, this context is passed by chatbot engine to a backend services to get a quotation. Backend services may be such services responsible to provide domain specific response to user queries which is a car insurance company in the present example embodiment. The quote may be presented to the end user as a personalized video. In this case, the intent is—“getting car insurance quote”. For each intent, responses may be configured as part of chatbot design/configuration. In this case, the response configured for successful quote generation may be a personalized video message. In case, some data is incomplete, or due to some reason quote is not available from the backend services, the response may be a text message.

Referring to FIG. 3 , conversational interface may receive data package as a response from the chatbot platform, as in step 304. The conversational interface may identify the format of the data package, as in step 306. If the format is at least one of the type, image, action button, forms, text, and/or video, the content may be extracted from the data package and may be presented in the conversational interface using such UI elements as defined in the configuration data. If the format is of the type ‘Personalized Smart Video’, the conversation interface may extract user data and information of attributes of the personalized video content, as in step 308. The attributes may be such as, but not limited to a video template and/or the video configuration metadata associated with the video template. The information of the attributes of the personalized video content may comprise information such as, but not limited to, user preferences for personalized video and/or storage location information (storage path) where a video template and associated video configuration metadata is stored in the PSV web server. The information of the attributes may be communicated to personalized video generation engine which may be configured to generate personalized video content. The personalized video generation engine may fetch video template and the video configuration metadata, as in step 310. The personalized video generation engine may generate one or more overlay elements, as in step 312. The one or more overlay elements are the transformed user data that are to be presented in the form of personalized video which are overlaid on the video template during playback of the video template. The video configuration metadata may be updated with user data to generate overlay elements and the placeholders of the video template may be populated with overlay elements, as in step 314. Then, the personalized video content may be displayed within the conversational interface by dynamically arranging the overlay elements during the playback of the video template, as in step 316. Optionally, the personalized video content may be displayed outside the conversational interface using browser embedded video player associated with the web browser.

In an example embodiment, consider a case wherein a wellness reminder to be communicated to the user. The user may log-in to a healthcare portal which comprises a chat application. The user may respond to view the message. The chat application may capture user message (or input) and send it as user utterance to a chatbot platform. The chatbot platform comprises chatbot engine which may process the request from the user. The chatbot engine may interpret user message (utterance) and may identify user intent using NLP component. The chatbot engine may identify response based on the intent identified by NLP component. The chatbot engine may fetch user data from the external data source (which may be healthcare account management services) comprising username of the user, name of the contact persons and contact number of the persons. Based on the intent, the response may be identified to be personalized video message with user data such as username, several contact numbers of healthcare service and name of contact persons. The chatbot engine may send the identified response to response generator. The response generator may receive the response from chatbot engine and identifies the type of response widget. The response generator may fetch the configurations of the widget from response widget library, which will contain configurations for the response type ‘Personalized Smart Video’ (PSV). The response generator may compose a data package by appending the user data (username, contacts, and contact person name) to the response widget which comprises path to the video template and video configuration metadata. The composed data package may be sent to the chat application. The chat application on browser interprets the type of message to be PSV and invokes the personalized video generation engine.

The personalized video generation engine may fetch the video template and video configuration metadata from the PSV web server. The video template may be a wellness reminder template with placeholders to show username, contact person name and contact numbers. The user data may be appended to the video configuration metadata to create an updated video configuration metadata. The updated video configuration metadata may be parsed to create overlay elements which are nothing but transformed user data which suits the format of personalized video as per the configuration defined in the video configuration metadata. The one or more placeholders may be populated as per the association rules defined in the video configuration metadata. The personalized video generation engine may invoke a video player at run time using PSV player component. The PSV player component plays the video template and renders the personalized video message within the chat window of the chat application by dynamically arranging overlay elements on top of the respective placeholders in each frame of the video template.

In one or more embodiments, a non-transitory computer readable storage medium for dynamic generation of a personalized video content in a conversational interface using web technologies. The method comprising, receiving an input from a user though a conversational interface at a client device associated with the user. As a response to the user device, a data package is received from a conversation engine communicatively coupled to the client device over a computer network. The format of the data package received at the client device is identified. On determining that the format of the data package is of type ‘Personalized Smart Video’, a user data and information of the attributes of the personalized video content is extracted from the data package. The attributes of the personalized video content are received at the client device from a storage server, the attributes comprising at least one video template and a video configuration metadata file associated with the at least one video template. A personalized video content is displayed at the client device.

The step of displaying the personalized video content, comprises, appending the extracted user data to the video configuration metadata file to generate an updated video configuration metadata file. The updated video configuration metadata file may be parsed to generate one or more overlay elements. The at least one video template may comprise one or more placeholders. The one or more place holders may be populated with the one or more overlay elements. The personalized video content may be displayed by dynamically arranging the one or more overlay elements over the video template based on one or more predefined rules. The personalized video content may be displayed within the conversational interface or may be popped out from the conversational interface and played using browser embedded video player at the client device.

The personalized video may be used to communicate personalized information to a user in way by improving the presentation to the user. The advantage of the technology described in the present disclosure is that the overlay elements are not pre-processed or created at server side before being rendered on screen for the end user. Instead the overlay elements (information that needs to be communicated to the user) are overlaid in real-time on video using web technologies/browser capabilities available at the client device. The capabilities of the web technologies are harnessed to take personalized video watching experience to the next level. Instead of creating one video per person, the described technology reuses a single video template for a personalization campaign and overlay the personalization parameters on top of the video template using browser capabilities at the client device. The video file is not created but the video template is dynamically personalized in real-time based on user data. The disclosed technology may be used to deliver personalized communication in Business-to-Customer (B2C) scenarios for various stages of customer interactions (e.g. prospects, onboarding, reminders) in various domains without spending much on processing power and storage resources.
